Definitions

  • the invention relates to an electromotive actuator drive for valves, slide cd. Like. With torque-dependent end position switch-off of the locking piece arranged on a rod by means of a switching element arranged at the end of a hat spindle which is sprung by means of disc springs or the like, which acts on limit switches, and a handwheel serving as a spindle nut and surrounding the lifting spindle as a coupling and as a rotation lock for the rod.
  • the object of the invention is therefore to improve an actuator drive of the aforementioned type in such a way that the closure piece can be set to different intermediate positions in a structurally simple manner and safely without changing the earth circuit (closing or whole open position), the intermediate positions in their setting should be controllable and adjustable from the outside.
  • this object is achieved in a generic actuator drive in that two additional limit the path of the rod in an upper and / or lower intermediate position arranged de and parallel to their direction of movement / stroke-dependent stops, which can be changed from the outside on or in the partially open housing are arranged, are provided.
  • the housing is interrupted e.g. partially open to the outside due to cage-like design, so that the stops can be checked and / or easily changed by hand.
  • stops are designed to be adjustable by displacement or twisting, any intermediate positions can be set in a simple manner.
  • a housing 12 designed as a cage for the actuator drive is attached to a three-way valve 10 with a closure piece 11 such as a valve plate or valve cone.
  • a non-rotatable valve rod 13 arranged on the closure piece 11 protrudes into the housing 12 and is fastened on the earth side to a disk-shaped handwheel 14 acting as a spindle nut that is T-shaped in cross-section.
  • a threaded bore 16 is machined centrally in an extension 15 of this handwheel 14 and in the extension of the valve rod 13, into which a rotatable lifting spindle 17 with an external thread 18 is screwed.
  • This jack screw 17 passes through a cup-shaped housing 19 in which a plurality of ring disks 20 comprising the top spindle 17 are arranged, a lower ring disk 20 on the cup-shaped housing bottom 19 and an upper ring disk 20 on a screwed-on cover which closes the housing 19. 21 supports.
  • the middle two washers 2 0 which divide the interior of the housing 19 into two chambers 22, in each of which two plate springs 23 are arranged, which surround the lifting spindle 17, are axially by means of a cotter pin 24, socket bolts or the like on the lifting spindle 17 limited storage and compress the plate springs 23 in the axial direction to trigger the switching process.
  • a larger gear 25 encompasses the lifting spindle 17 and meshes with a smaller gear 26 which can be driven by an electric motor 27.
  • the gear space 28 provided at the top in the housing 12 for receiving the two gear wheels is likewise closed off by a removable cover 29, through which the upper end of the lifting spindle 17 is guided.
  • a rotary disc 3c At the free end of this lifting spindle 17 outside of the housing 12, there is a rotary disc 3c, which is rotated alternately left and right when the cap spindle 17 rotates and actuates an upper or lower limit switch 31 attached to the housing 12 during the axial displacement of the lifting spindle 17 which the electric motor 27 is switched as soon as the closure piece 11 has reached one of its end positions.
  • valve rod 13 moves up and down without rotation, the handwheel 14 being fixed against inadvertent rotation by means of a spring-loaded locking bolt 32, the free end of which can be pulled out into a longitudinal groove 33 in the handwheel 14.
  • This locking bolt 32 is mounted in a housing 3a, which is screwed at right angles to the lifting spindle 17 into a / webs 35 of the housing cage 12 by means of a thread and receives a spring 32b inside.
  • the spring 32b presses with one spring end on an annular shoulder 32c located on the locking bolt 32, while the other spring end presses against a clamping ring 32d fastened in the housing 32a, so that the locking bolt 32 is always pressed in the direction of the longitudinal groove 33.
  • the handwheel 14 is to be adjusted in height, the locking bolt 32 is pulled out of the longitudinal groove 33 by means of a knurled disk 32e.
  • the handwheel 14 is free and can be rotated until the desired height is reached and the locking bolt 32 can snap back into place.
  • the housing 32a is provided on the outside with a vertical slot 32f into which a Locking pin 32 engages in the area of the knurled disk 32e, fixed pin 32g, which is held so that it can be pulled out of the slot 32f with the locking pin 32 (see FIG. 3).
  • this training which is known per se, is improved by a separate travel-dependent training (circuit).
  • a separate travel-dependent training (circuit)
  • a web 35 designed as a cage (i.e. partially open) housing 12 at a certain distance an upper by means of screw 36 or the like.
  • adjustable stop 37 and a corresponding lower adjustable stop 38 mounted.
  • These stops 37, 38 have the task that the locking piece 11 can assume any intermediate position within the stroke range, e.g. with certain gas fittings, where a smaller amount of gas must be guaranteed to maintain the pilot light.
  • the stroke limitation of the valve rod 13 is instead of the stops 37.38 from one of the valve rod 13 with the other identical design Hand wheel 39 and are formed one on one, the / valve rod 13 surrounding threaded projection 4 0, adjustable nut 41 in one direction and a screwed VCN and on the cup-shaped housing 19 adjustable nut 42 in the other direction 14 connecting nut.
  • the stroke of the handwheel 14 is limited in the axial direction by correspondingly turning the nuts 41, 42.
  • the housing 12 is designed as a cage and thus partially open, the nuts 39, 41 and 42 acting as stops can also be checked in their position and their position can be changed slightly from the outside.
  • any intermediate position for the closure piece 11 can be selected.
  • the handwheel 14 can be rotated by hand after pulling out the locking bolt 32 in such a way that the closure piece 11 also reaches its desired end position in order to open or close the valve in whole or in part.
